Long term effects of Agent Orange in Viet Nam

A LUOI, VIET NAM - JUNE 28: Acacia trees are planted in a new plantation on June 28, 2009 in A Luoi Valley in Central Viet Nam.The valley was one of the areas heavily exposed to Agent Orange during the Viet Nam War. Acacia trees were began planted by the Viet Namese government in mid-1990s as a reforestation program of the mountains, which used to be home to triple canopy jungles. Although Acacia trees can provide local residents with a way of earning money, the quality of the plantations decrease after 3 to 5 harvests, posing new problems for reforestation.
